Fluid mechanics calculation problems
Thread Content
I’m seeking help from experts: As shown in the attachment, the pressure and flow rate downstream of the control valve are known. The pipe diameter is known. Furthermore, the pipelines at points A and B are completely symmetric, and the heights of each point are known. It is necessary to determine the pressure loss up to point A as well as the velocity at point A using appropriate methods What I’m considering is using the constant flow rate to determine the velocity at point A, and then applying Bernoulli’s equation to find the pressure loss. The Hf value can be found in the table and then used for calculation. With such an algorithm, the resulting loss of kinetic energy is not sufficient to raise the liquid to the height of point A. I don’t know what’s wrong with my way of thinking; please help me take a look.
I’m supposed to help you solve problems and still pay you money!
I’m sorry for not being clear in my first post
